What Trees Produce Keys

Ash and elm trees also have keys, but maples are the best fliers. In fact, scientists study the design of maple keys to help them create micro-flying machines and to develop miniature helicopters for space exploration. The wing of the key becomes wider at the end that does not contain the seed.

Which maple trees do not have helicopters?

• Firefall maple (zones 3-7): A cherry-red maple that can endure ice, snow, and harsh wind.
• Celebration maple (zones 3-8): A tree with bright orange and yellow fall leaves that can deal with drought, frost, and storms.
